in-which similar figures of reference indicate corresponding parts in all the views.

Figure l is a. cross-section of the boiler 55 embodying myinvention with parts of the tubes broken sway. Fig. 2 is a vertical section on the line 2 2 of Fig. 1. Fig. 3 is o detailY sectional View on the line 3 of Fig.v Vv1', showing v'the outside connection between the headers 6o on one side of the boi-iemand Fig. 4 is a detail View in elevation of two adjacent headers.

The boiler is provided with the customorv steam-drum 10, from opposite ends of which extend downward Vand outward the down- 65 tokeiies 11, which are curved, as shown, and elivered into the topsV of the vertienl mud-drums 12, which ere nrrenved at the oor 11ers of the boiler, and are oli'set from the henders 18 and lhereinsfter referred .to and os 7o shown by dotted lines in Fig. l. The 1nuddrums are protected on the inner side by lirobriek 1.3 and are connected both ways of the boilerwthat is, across the ends and sides-why the pipes I4. The mud-drums 12 also L'on- 75 neet neer the bottoni by the elbow-pipes 15 and 16 Withthe headers 18 and 19, the joints of the pipes 15 and 16 being provided with plugs 17 ,so that the pipes can be easily gotten at vwhen necessary. Y. 3

The headers 18 and 19 are errenc'ed in pairs, each header IS-hsving a relotive v ner# row Vtop extension 18, and each header 19 having s relatively wide top extension 191, sol that the headers interlock, as shown in Fig. 2. 85 to forni' `the side of a boiler. 4

Headers on opposite sides are connect ed :by the inclined Water-tubes 20,111050 being ori ranged in rows, each rioniy unirmeting4 the norrow part of a. heafherA 18 01219, ns the case 9o may be, with the nnrrow )ort of the header opposite. The rows o'tnloes .20 are also en# tended down, so that they extvmlfgrmnthe; narrow part 19 of :i header to the wider par( 1b of the' hendel' opposite, which arrangement 95 brhigs the tubes Well dowii Vin 1 ih e narrow. parts of' the headers, but leaves n blilnklspneo u on then'ider perte of the opposite hegldvls 1 8( Vas shonh 'clearly 'r'gL f3. This rriinge nient. enables Ythe simi-elio be substantiallyl :oo

site heodrs `areConnected also vbv tn n rows., 26 offtuh'es.,4 'lrhooutside's of the houders are proided opposite the pipes with screwplugs Y2l. which can be removed easily in case any pipe needs to be scraped oi' repaired. 'lo provide for circulation in case the pipes of anrheader become clogged or in case any connections are interfered with, I arrange on the outer side of the boiler-wiill couplings 22, which connect from header to header, as shown in Fig. 3, and the couplings have straight legs 23, which are screw-threaded on the outer side, so that certain special appliances can be attached thereto for repairing or scraping a tube, and the straight legs are `closed b plugs 24.

It will be noticed that the'arrangeinent of tubes and headers makes both parts very accessible and utilizes heat ing-space of the boiler to a great extent; but there is still a little space above the rows 20 of tubes, and inl this space I arrange t-he bent tubes 25,"which extend from the upper jportions of alternate headers, as shown 1n Fig. 1 and 2, to the'A steam-drum 10. Thus 1t will be seen that byd the compact arrangement of tubes 2O and 25 I 'utilize the whole heating-space, and the boiler will therefore steam economically; The upper end of the headers "are also conneoted to the steam-drum by short pipes 26.

It'will be observed that the arrangement of yertical mud-drums, the' connection between the mud-dr 1 and the steam-drum and the connection etween the mud-drums, headers,

and. water-tubes, and between'thelatter and the\stean1dru1n, is such that a perfect circulatiotn is provided and such also as to make injurious clogging very unlikely. It will be noticelhtoo, that there is an ample downllow connection through the ipes 11 from the steam-drum to the mudrums, that there is a sure connection between the latter -and the headers 18 and 19, and that the headers being connected at top and bottom with steamdrum and mud-drums, and also connected to ether bythe couplin s 22, are little likelv to e'njuriously clogge or affected. It will be seen, too, that the connections are so ample between the' headers and between the head ers, mud-drums, and steam-drum that in .casca connection or more becomes 'clog ed the circulationl can continue through ot er connections. It will be seen also that the lower watervtubes,.which arey most likely to burn, can be taken out or inserted through the tire-box without disturbin aheader.

VHaving thus full descri ed my invention, I claim as new an desire to secure by Letters Patentl ,1. QA' boiler of the kind `described comprisin alternating headers forming the boiler si es, each headerhaving Va relatively wide section and a relatively narrow section with `said wide and narrow sections alternately arran ed, cross-tubes arrangedin rows and extending from the narrow part of one header to the narrow4 part of the opposite header the lsame row also connecting with the wider part oi the header opposite and also between the wide parts ofthe opposite headers, whereby there are three rows of tubes counecting opposite headers, a steam-drum connected with theheaders, Vertical mud-drums forming the boiler corners and. connected to the headers, and downilow-pipes extending from the steam-drinn to the mud-drums.

2. A steam-boiler comprising a series of headers forming its side walls, the headers on each side being alternately arranged and constructed so that one is wider at the bottom andnarrower at the top, the next narrower at the bottom and wider at the top and so on, inclined cross-tubes extending from header to header, there being at least three rows of tubes entering uthe wider parts and a single row enter-ing the narrow parts and suitable steam and mud drums connected with the upperV and lower parts of the headers.
